Title: Quartz pipe joint structure
Inventor: HASUWA TAKURO
IPC: F16L19/065
Filed: 2021-11-18
Abstract: To provide quartz pipe joint structure capable of keeping high effect of sealing even when used under high-temperature/high-pressure conditions for a long time.SOLUTION: A quartz pipe includes a circumferential groove in an outer periphery. An outer cylinder portion of a joint main body includes a male screw on an outer periphery, and houses an end portion of the quartz pipe on an inner peripheral side. An inner cylinder portion of the joint main body is surrounded with the outer cylinder portion, and the outer periphery of the inner cylinder portion and the inner periphery of the outer cylinder portion form an annular groove. A ferrule surrounds the end portion of the quartz pipe between the end portion of the quartz pipe and the groove, and closes a gap between the outer peripheral portion of the quartz pipe and the inner periphery of the outer cylinder portion. A stopper surrounds the quartz pipe at the same place with the groove of the quartz pipe, and comes into contact with the ferrule and an inner surface of the groove of the quartz pipe. A union nut houses the quartz pipe, ferrule and stopper on an inner peripheral side, and applies to the stopper, axial force generated by coupling of the male screw of the outer cylinder portion and a female screw thereof. Consequently, the stopper presses the ferrule against the outer periphery of the quartz pipe and the inner periphery of the outer cylinder portion and also forces a distal end of the quartz pipe into the annular groove.SELECTED DRAWING: Figure 2
